You do need to describe the method you are using. Might help others with the same problem.
Depending on noise filter, you get multi-coloured pixels, and if transparency is introduced often looks like they are still there. I think, depending on image size and parameters there are usually too many stars. Other than desaturate, there is Colors -> Threshold which reduces to black & white.

I might do this: Use Hurl noise with minimum values https://i.imgur.com/5cS3r02.jpg
Apply Colors -> Threshold with the left slider almost maxed out (value here 252) That reduces the number of stars. https://i.imgur.com/mOrvENq.jpg
Again, depending on size of image, make the noise (stars) larger, Filters -> Generic -> Dilate. https://i.imgur.com/zwYrAqX.jpg
On the other hand, there is a script to produce starry-skys
